Description/Features
The centertap Schottky reCWermodule has been optimized for
ultra low forward voltage drop specifically for the OR-ing of
parallel power supplies. The proprietary barrier technology
allows for reliable operation up to 125 ''Clunction temperature.
Typical applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
